However, in the process of producing a plate separation using such a conventional printing apparatus, the image of the page was initially drawn until the plates were overlaid and printed. I wasn't able to confirm whether or not it matched. In addition, since each separation is manufactured separately, it is difficult to understand the interrelationship between the separations, and it requires skill to determine which separation should be modified in order to correct the quality of color printing.

Further, if the number of types of print data is large, the number of color separations increases remarkably, so that the labor for managing what data is set to print in which color separation is increased, and the print result can be confirmed. It was necessary to repeat the number of times of printing according to the number of separations.

An M3, an input unit 4, a display unit 5, and a printer 6 are provided in common, and in addition to this configuration, various information for printing the document file in the document file storage unit 7 is provided in a part of the memory area of the RAM 3. This is a configuration in which a print information storage unit 8 for storing is provided.

The CPU 1 arithmetically processes the data input from the input section 4 according to the program recorded in the ROM 2, and displays the arithmetic result on the display device 5 or the printer 6 as a print result. This CP
When designating the output data, U1 controls the designation procedure so that the print data designated by any of the output data information can be confirmed. Further, a part of the data subjected to the arithmetic processing is temporarily stored in the RAM 3 and used for the subsequent arithmetic operations. Particularly, the document data of the original is stored in the memory area secured as the document file storage unit 7 inside the RAM 3 and used for the subsequent editing.

FIG. 2 is a diagram showing the structure of a document file stored in the document file storage unit 7. In the document file, the name of the document is the file name 21, the output format of printing such as the paper size and pillar information of the manuscript and the page number is the format information 22, the character code string is the text data (character code string) 23, and the table or figure The two-dimensional information is stored as table data 24 and graphic data 25, and the image information is stored as image data 26 in the respective memory areas.

FIG. 3A is a diagram showing the structure of the print information stored in the print information storage unit 8. The print information is information for printing the document stored as the document file name, and the CPU 1 controls the printing based on this print information. The print information includes a print file name 31 that specifies a document file to be printed, a print page 32 that indicates the range of pages that are actually printed, a print number 33 that indicates the number of copies to be printed, a separation number 34, and the first version output data. It is composed of information 35, second edition output data information 36, Nth edition output data information 37 and the like. The number of plate separations 34 indicates how many plates the document to be subjected to the plate separation printing is divided into, and is automatically set by the setting of the plate separation printing described later. The first edition output data information 35 outputs which print element among the print elements (in this embodiment, the number, the pillar, the sentence, the table, the figure, the image) included in the document file to the first edition. The information that is stored in the second
The version output data information 36 to the Nth version output data information 37 have the same structure. Of course, N is equal to the number of plates 34.

FIG. 3B shows the nth version output data information 38.
3 is a detailed data structure diagram of FIG. In this embodiment, an example of 8-bit data structure is shown. Each bit corresponds to each print element, and corresponds to the sentence 41, the table 42, the figure 43, the image 44, the number 45, and the pillar 46. Of the print elements set or stored in the document file, which print element is to be output in the nth version is set by ON or OFF of each bit.

FIG. 3C shows the nth version output data information 38.
5 is a detailed data structure diagram of output data setting information 39 which is temporarily set in the RAM 3 during the setting process of FIG. The correspondence between the data structure and the bits is the same as that of the nth version output data information 38, and the description will not be repeated.

The output data setting information 39 is used as a buffer when setting the nth version output data information 38. That is, when the print element to be output to the nth plate is selected by the user's instruction from the input unit 4, the bit corresponding to the selected print element of the output data setting information 39 is turned on. On the contrary, when there is a non-selection instruction from the input unit 4 for the print element once selected, the corresponding bit is turned off. In this way, after only the printing elements to be output to the nth plate are set to ON, the output data setting information 39 is set to the nth plate output data information 38, so that the printing to be output to the nth plate is performed. The element settings are complete.

FIG. 4 shows the first version output data information 35 and the second version.
It is a figure showing the principle of the method of calculating | requiring the output data setting information 39 from the plate output data information 36. In the example shown in the figure, the OR element 58 obtains the logical sum of each bit of the first version output data information 35 and the second version output data information 36, and when the bit is inverted by the inverter element 59, the output data setting information 39 is obtained. Desired. Although FIG. 4 shows an example of the first edition and the second edition, in reality, the first edition to the (n-
1) It goes without saying that the logical sum of the output data information of the version is obtained.

FIG. 5 is a view showing a color separation setting menu 67 displayed on the display device 5. In the drawing, print elements (from the text 61 to the pillar 66) are displayed, each of which is marked based on the output data setting information 39, and the user should output to the nth version by this separation setting menu 67. Set print elements. In the color separation setting menu 67, the white circle mark is a print element that is not selected in the nth version and corresponds to the bit OFF of the output data setting information 39 (see FIG. 4), and the black circle mark is selected in the nth version. Is a printing element corresponding to bit ON. As described above, in the output data setting information 39, the bits in the ON state among the print elements that have not been set as the default value in the first to (n-1) th versions are set as information. Therefore, the user can easily know the printing elements that have not been selected by the separation setting menu 67.

FIG. 6 is a diagram showing a process of producing a plate separation using the plate separation printing apparatus in one embodiment of the present invention. In the figure, 71 represents a completed page. This page 71 includes print data of a sentence 61, a table 62, a figure 63, an image 64, a page 65, and a pillar 66. Further, in the case of color printing, print data of three primary colors is included in each. The creator of the separation is such a page 71
Is input to the color separation printing apparatus as one document file by the input unit 4. Next, when the print information is set as required and a separation print command is given, the printer 6 separates the separation plates 72 to 7.
6 is obtained. That is, 72 is the number 65 and the pillar 66.
Is the set separation. Reference numeral 73 is a separation in which the sentence 61 is set. 74, 75, and 76 are color separations in which a table 62, a figure 63, and an image 64 for the first primary color (yellow), the second primary color (magenta), and the third primary color (cyan) are set.

The operation of the color separation printing apparatus having the above structure according to the embodiment of the present invention will be described below with reference to FIGS. 6, 7, 8 and 9. It is assumed that the creator of the color separation plate has just input the document file of page 71 as shown in FIG. 6 into the document file storage unit 7 of the color separation printer by operating the input unit 4.

FIG. 7 is a flowchart showing the initial setting of print information. The maker of the plate separation operates the input unit 4 to activate a program for setting print information in the print information storage unit 8. The CPU 1 starts arithmetic processing for setting print information according to the program stored in the ROM 2.

First, the print information stored in the print information storage section 8 is set to the initial state, the number of plates 34 is set to 1, and all the bits of the output data setting information 39 are ON (selected state).
Are respectively set (S1). Next, the color separation setting menu 67 is displayed on the display device 5 to prompt the manufacturer to select print elements. The output data setting information 39 is all ON
Since the initial setting is (selected state), each printing element of the color separation setting menu 67 is a black circle mark indicating the selected state (S2). Here, according to the color separation setting menu 67, an instruction to deselect a print element is waited for (S3), the bit of the output data setting information 39 corresponding to the non-selected print element is changed to OFF, and the bit corresponding to the color separation setting menu 67 is changed. The printing element to be changed is changed to a non-selected white circle mark (S4). After that, the content of the output data setting information 39 is copied to the first version output data information 35 (S5), the number of plates 34 is added to the current number n, the initial setting is completed, and the setting of the next plate is started ( S6).

FIG. 8 is a flow chart showing the setting of color separation printing after the second edition. In the figure, the OR element 58 calculates a logical sum for each bit from the first version output data information 35 to the (n-1) th version output data information (S7). The result of step S7 is bit-inverted by the inverter element 59 and set in the output data setting information 39 (S8).

In the example of FIG. 4, in the first version output data information 35, the bits of the number 45 and the pillar 46 are ON,
In the first edition, the number 65 and the pillar 66 are set. Similarly, in the second edition output data information 36, the bit of the sentence 41 is ON, and the sentence 61 is set in the second edition. Output data setting information 39 is obtained by obtaining the logical sum of these and inverting the bits. As a result, the output data setting information 39
Of text 51, page number 55, and pillar 56 are OF
It becomes F (non-selected state). Therefore, the print element selected in any of the versions from the first version output data information 35 to the (n-1) th version output data information is OFF in the output data setting information 39. Therefore, the creator of the color separation can perform the setting without omission without paying particular attention to what print data has been set in the past.

The color separation setting menu 67 is displayed on the display device 5 based on the output data setting information 39 set in step S8. In the example of FIG. 4, the sentence 51 and the page number 55
Since the bit of the column 56 is OFF, it is displayed as a white circle mark (S9). At this time, wait for an instruction from the input unit 4 (S10), and if there is a change, output data setting information 3
After inverting the corresponding bit of 9 (S11), if there is no change, the content of the output data setting information 39 is changed to the nth value.
The plate output data information 38 is set in the print information in the print information storage unit 8 (S12). As described above, the series of nth version output data information is set, and the CPU 1 sets the ROM 2
According to the program, the display device 5 displays whether or not the plate number 34 should be updated and prompts the manufacturer to input (S1).
3). To continue updating, n of the number of plates 34 is incremented by n + 1, the process returns to step S7, and the operations up to step S13 are repeated (S14). When the update is not performed, n of the number of plate separation 34 is set as the number of plate separation N in the print information in the print information storage unit 8 and the setting of the plate separation printing is completed (S15).

In this way, the nth version output data information 38 for managing the print data of each version, and the separation setting menu 6
Since the output data setting information 39 for displaying 7 can be entrusted to the arithmetic processing of the CPU 1 as bit-corresponding data, it is possible to realize the automation of the separation printing setting and the sequence management of the setting procedure. .

A process for performing the separation printing of the relevant document based on the print information set as described above will be described. FIG. 9 is a flowchart showing the process of color separation printing. The creator of the plate separation operates the input unit 4 to start a program for performing plate separation printing of the document file based on the print information set in the print information storage unit 8. The CPU 1 starts arithmetic processing for performing color separation printing according to the program stored in the ROM 2. First, the current version number t (indicating what version the version currently being processed is) is initially set to 1 (that is, the current version number t = 1) (S21). Next, the first version output data information 35 of the print information set in the print information storage unit 8 is referred to (S22). As a result of the reference, the print element to be subjected to the color separation printing is determined from the bit set to ON (S23). In the example of FIG. 4, the first edition output data information 35 to the number 4
5 and pillar 46 correspond. A document file to be subjected to color separation printing is read from the document file storage unit 7, data to be printed is extracted, and color separation print data is created (S24). Figure 6
In the example, the color separation print data of the color separation 72 is created from the page 71. The color separation print data is transmitted to the printer 6 and the color separation 72 is color-separated and printed (S25). After performing the plate separation printing of the plate, it is checked whether the current plate number is equal to the plate separation number N (S26). If they are not equal, the color separation printing is continued, the current plate number t is incremented by 1, the process returns to step S22, and step S2
The operations up to 5 are repeated (S27). If they are equal, the color separation printing is stopped and the color separation printing ends.

As described above, since the separation printing can be directly performed from one document file, no skill is required for producing the separation, and the work of actually printing to confirm the quality is not necessary. Became.
